Beta-Hydroxyisovaleric acid (also known as 3-hydroxyisovaleric acid or 3HIA) is a normal human metabolite excreted in the urine. It is a byproduct of the leucine degradation pathway. Beta-Hydroxyisovaleric acid serves as a sensitive indicator of marginal biotin deficiency in humans. The variability of the proportion of leucine catabolites excreted as 3HIA suggests substantial population heterogeneity in the metabolic capacity of the 3HIA-carnitine detoxification pathway. In addition, was shown that in type II diabetic patients the catabolism of leucine was accelerated even in the absence of ketosis and that the urinary beta-hydroxyisovaleric acid concentration was a useful marker of short-term metabolic control in these patients.

Beta-acetyldigoxin (under the brand name Novodigal), a beta-acetyl derivative of digoxin, acts as a prodrug. It is deacetylated in the cells of the intestinal mucosa and is present inside the body solely in the form of digoxin. β-acetyldigoxin has a higher bioavailability than digoxin. Beta-acetyldigoxin is a substrate of P-glycoprotein.

4-Amino-3-hydroxybutanoic acid (GABOB) is an endogenous ligand found in the central nervous system in mammals. γ-Amino-β-hydroxybutyric acid is a derivative of the neurotransmitter GABA. It has been claimed to be of value in neurological disorders and to have an antihypertensive effect. γ-Amino-β-hydroxybutyric acid can help overcome stress and anxiety, improve learning and boost memory function. It is also known to increase growth hormone levels, which help the body heal and rejuvenate itself. There are no reported side effects of γ-Amino-β-hydroxybutyric acid when taken at therapeutic dosages. At high dosages, some slight drowsiness may occur. Adverse effects have included dizziness and anorexia also.

Morniflumate is a non-steroidal anti-inflammatory drug and represent as a beta-morpholinoethyl ester of niflumic acid, which is rapidly hydrolyzed in the plasma, releasing the free acidic form, the molecule responsible for the pharmacological effects. It was shown, that morniflumate was effective in the treatment of chronic recurring bronchitis and inhibited cyclooxygenase-1, 2 (COX-1, 2). Morniflumate has a 30-year history of clinical use, particularly for the treatment of pain associated with pediatric ear-nose-throat (ENT) infection. In addition, it appears to be a valid and well-tolerated alternative to other NSAIDs, or to antibiotics, for the treatment of pain and other symptoms of soft tissue inflammation.

Sodium glycerol 2-phosphate (Disodium beta-glycerophosphate) is used for the preparation of thermo-sensitive chitosan hydrogen as a scaffold to construct tissue engineered injectable nucleus pulposus (NP). Since Sodium glycerol 2-phosphate (6 g/day) reduced the lithogenic index of bile in human subjects with cholesterol gallstones in a short-term study and facilitated dissolution of cholesterol gallstones in mice, Sodium glycerol 2-phosphate may have potential to help dissolve cholesterol gallstones in man. Sodium glycerol 2-phosphate is an alkaline phosphate inhibitor. Sodium β-glycerophosphate pentahydrate is used as a phosphatase inhibitor. It promotes bone matrix mineralization while delivering to osteoblasts by providing a source of phosphate ions. It is used in the development of hydrogels and scaffolds, which finds applications in tissue engineering and cell growth. It is used as an additive in isolation mediums by providing phosphate ions to isolate. It is utilized to promote mineralization in vitro by modulating bone cell metabolic activity.

Nicoboxil is a nicotinate used in topical preparations as a rubefacient which has vasodilating properties mediated by prostaglandin. Nicoboxil is a component of finalgon® (nonivamid and nicoboxil), a topical cream for joint and muscle pains. The hyperaemic effect of Nicoboxil has an earlier onset and it is more intense than the nonivamide hyperaemic effect.

Gentamicin is an antibiotic of the aminoglycoside group, is derived by the growth of Micromonospora purpurea, an actinomycete. Gentamicin is a complex of three different closely related aminoglycoside sulfates, Gentamicins C1, C2, and C1a. Gentamicin is a broad-spectrum antibiotic, but may cause ear and kidney damage. Gentamicin binds to the prokaryotic ribosome, inhibiting protein synthesis in susceptible bacteria. It is bactericidal in vitro against Gram-positive and Gram-negative bacteria. Adverse reactions include adverse renal effects, neurotoxicity (dizziness, vertigo, tinnitus, roaring in the ears, hearing loss, peripheral neuropathy or encephalopathy), respiratory depression, lethargy, confusion, depression, visual disturbances, etc.
